Full Description

Since the advent of Supervisory Control and Data Acquisition (SCADA), water operators have been able to obtain vast amounts of data. Flows and pressures can be monitored over time to develop system profiles. This information allows the operator to optimize pressure and improve service to the customer. Pressure optimization can be achieved over a 24-hour period as the flow rates increase and decrease. The pressure can be increased as the demand rises and decreased as the demand diminishes. This methodology is defined as pressure modulation. Through pressure modulation a reduction in unaccounted-for water that is lost directly to leakage can be achieved. This is the prime objective of pressure management and the focus of this paper. Includes figures.
